This article evaluates the impact of legislation that established nutrition standards for competitive foods in California schools. Researchers found that regulation of competitive foods modestly improved school environments and student nutritional intake. Availability of nutrition standard-compliant foods and beverages increased, while availability of noncompliant items decreased. The authors conclude, however, that additional policies are needed to achieve more substantive improvements in school nutrition, since many nutrition standard-compliant foods are fat- and sugar-modified products with low nutritional value.
